Change your Xbox's system language to "Japanese" and then start the game. The original Japanese voices will replace the American ones.

While playing the game with either team sonic, dark, or etc. switch to fly formation then press and hold the x and y buttons at the same time. You will switch to power formation while the one who can fly will stay in the air until your gauge is power up by at least 35 percent. Do it as many times as you like.
